.SYRIN GE Application filed January 3, 1908.

To all whom "it may concern:

Be it known that I, HAnLoN FINLY ONG, a citizen of the United States,and a resident of Portland, in the county of Multnomah and State ofOregon, have invented a new and useful Improvement in Syringes, of whichthe following is a full, clear, and exact description.

The purpose of the invention is to provide compact syringe, one that canbe conveniently carried upon the person and one in which the piston isprovided with a chamber adapted to contain medical ingredients to bedissolved in the liquid to be injected.

It is a further purpose of the invention to so construct the piston thatit will be ermanently closed at its outer end, and so t rat the pistonhead will act as a stop er, since it is removable and admits of tab ets,powders, or granular or crystallized substances contained in the'body ofthe piston, being removed in desired quantities for introduction in thebarrel of the syringe, to be commingled with the liquid drawn therein.

The invention consists in the novel construction and combination of theseveral parts as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure 1 is a side elevation of the improved syringe, the parts being innormal po sition; and Fig. 2 is a longitudinal section through theinstrument drawn upon a larger scale, the parts being in operativeposition.

The instrument is preferably made mainly of glass, but rubber or othersuitable material may be employed in its construction if so desired. Thebarrel A of the syringe is provided with a conical outlet 10, as iscustomary, and is also provided with an open top 11, the material at thesaid top being flared outward to admit of the ready intro Specificationof Letters Patent.

Serial No. 409,150.

1 duction of a piston B. This piston B is tubular and is provided with aclosed upper end 12 and with a head 13 at its lower end, constructedpreferably of rubber, leather, or like material, ca able of clinging tothe inside of the barrel A into which the piston B is introduced.

In the chamber 14 formed in the piston B medicaments 15 are introduced,for example, tablets, as shown in the drawings, powder or crystallizedsubstances, and these introduced or received medicaments are held inplace by the piston head 13 that acts as a stopper to the piston. Hencethese medicaments are also in position for use, and by removing the head13 the material can be removed from the piston B and be placed in thebarrel A, so that when the piston is drawn upward or outward to draw inliquid, the liquid will mingle with the material introduced into thebarrel and will be ejected with it.

A syringe constructed as described is exceedingly simple, and enables acharge to be carried and protected in the article itself.

Having thus described my invention, I claim as new and desire to secureby Letters Patent,-

1. A syringe, comprising a barrel, and a piston having a hollow bodyforming a storage chamber for medicaments and provided with a removableiston head forming a closure for the said 0 iamber.

2. A syringe, comprising a barrel, and a piston formed of a hollow bodyopen at its inner end and forming a storage chamber for medicaments, anda removable piston head in the form of a plug fitting in the open end ofthe body and forming a closure therefor.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
